I COMPOSITE RAIL.

Specification of Letters Patent.

Patented Apr. 29, 1913.

Application filed March 9, 1912. Serial N 0. 682,641.

' which the rail head isremovably secured to to the base or the rail base.

It has heretofore been proposed to con struct a built up rail havinga removable head provided with integral flanges are ranged to engage with the railbase in securing the head to the base. In another construction the rail base has beenprovided with integral flanges which are bent into interlocking engagement with the railhead in securing the rail head to the rail base. 1

In the first mentioned construction the necessity of'bending the flanges on the rails head into engagement with the base restricts the composition of the head to one which is sufficientl. soft to permit bending of the flanges t ereon -into "locking engagement with the rail head. In the lastdescribed construction, straightening of the bent flanges of the rail base to release the-rail head in replacing or removi the head, seriously'weakens and lessens t e strength of the flanges and often requires the renewal of the rail base, an operation requiring the removal of the base from the track in which it is permanently secured in place.

One objectof my invention is to provide a composite rail having improved means whereby the removable rail head is secured girder forming the base of the rail. 4 Y Another object of the invention is to provide a composite rail having novel means whereby the rail head may be made of any desired composition and the necessity of limiting the degree of hardness of the rail head is avoided-and overcome.

A still further object of this invention is to provide a composite rail having novel means whereby the rail head is secured to the rail base in such manner as to permit the removal and renewal of the rail head without damage or liability of weakening or 1n ur1ng the'rall base or necessitating the removalv of the railbase, and whereby the rail base remains permanently fixed in place in the roadbed of the track after once being laid.

Further objects of my invention will appear hereinafter as my improved track rail is more fully disclosed in the specification and claims.

Referring to the drawings forming part of this specification, Figure 1 is an end elevationshowing one form of a composite track rail constructed and arranged in ac: cordance with my invention. Fig. 2 isa similar end elevation-showing a modified form of rail head and having head securing means constructed in accordance with this invention. Fig. 3 is an end elevation of a composlte guard rail for street railway tracks constructed and arranged in accord- 1 "ance with my invention. Fig. 4 is a similar end elevatlon'showmg a modified form. of

head as constructed for use on a girder rail for street railway tracks in accordance with this invention. I

In. the drawings, referring to Fig. l, the numeral 2 designates the head of a composite track rail constructed and arranged in ac cordance with this invention, and 3 is the top flange joined integrally by the vertical Web 4 to the base flange 5 in forming the rail base. An interlockmg member comprismg a connecting web port1on'6 with integral oppositely extending flanges 7, 8 and 9, 10

on the marginal side edges thereof is interposedbetweenthe rail head 2 and the top flange 3 of the rail base in securing the head and base together. The rail head 2'shown in Fig. 1 "has longitudinally extending grooves or recesses 11 located in the opposite side edges thereof into which the flanges 7 and 9 are bent into interlocking engagement in securing the rail head 2 to the top flanges 7 and 9 of the interlocking member. The flanges 8 and 10 on the opposite side of the web 6 of this interlocking member are bent downwardly and inwardly into interlocking engagement with the marginal edges of the top flange 3 on the rail base in securing the interlocking member to the. rail base.

In the modified construction shown in Fig. 2 the head 2" of the rail is provided vvith outwardly extending flanges 12, 12 011 I the loweredgeof the marginal side surfaces,

which projectoutward'ly beyond the faces of the sides of the'rail head 2, In this constructio-n. the flanges 7",, 9, of" the interlocking member-are bent upwardly and int-- Wardly into engagement with the flanges 12,-

the top flanges- '3 of the rail base and the top flanges 3, 3 are connected to'the base flange 5 by'an integralweb-f in the same manner as in Fig. 1

In the construction shown. "Fig. 3, the

' head '2 of the guard rail shown in this. figure is provided on one side with'a flange '13,

which is curved -.or bent to form a groove 14 in one sidethereofjadapted to receive the flange of the trackwheels, The opposite sidesurfaces 2 of the head 2' are provided with longitudinally extending recesses or grooves -11 into which the 'fianges 7 39", ofi the interlocking member are bent in securing the rail headto the interlocking member of the rail; The bottom flanges 8 10 ofthe interlocking member are bent downwardly and inwardly about the side-edges of the top-7' flanges 3", 3 of the rail base in the same manner as in the preceding figures, and the rail base in this construction is-likewise formed of top flanges 3 3 and base flanges 5 5 connected to the marginal-side edges;

of an integral web 4". v

In theconstruction shown in Fig. 4;".tl'16 2 mil headl2 is provided-with a horizontally extending flange portion 15 projecting side wise from one side thereof, and the head,2

in this construction has lengthwise extend, ing grooves 11. into which the upper flanges 7 and 9 of the interlocking memberare bent in securing the head 2 theret0.' -Thei,bot-

,tom flanges 8, 10, of the interlocking mem-' her are bent downwardly and inwardly around the side edges of the topsfianges 3, 3 of the'base member in the same manner as in the preceding figures, and the basemember of this rail is formed of top' flanges 3, 3

and base flanges 5 connected by an integral web portion 4 in the same manner as has been before described; l

The advantages of iii-Y, invention will be apparent to those skilled in the art.-: In my improved composite rail the rail head is secured to the rail base by" separate and independent interlocking members. 1

By making the interlocking member sepa-' rate and independent of the head and base of the rail, the rail head may be made as hard as is desired, as there are'no portions thereof which must be soft and ductile enou h to permit-bending in securing the head in'place.

any desired compositionwhich may dider The rail base can be made of.

greatlyfron'rthatof the rail head; Thain iterlocking member may 'be made of metal which willpermit of its being readily bent engagement with the head and baseof the to secure the flanges thereof in interlocking frail, Byinaking the interlocking member separate from the baseof "the ra l the rail and the necessity of removing the rail base rails is avoided-and overcome.
